Disable secure-http config option for unsafe configured PECL website

[tntrex]

This change allows to download extensions from PECL using http, when PICKLE_PECL_UNSAFE environment variable specified

[mlocati]

Shouldn't we already use http://pecl.php.net instead of https://pecl.php.net if PICKLE_PECL_UNSAFE is set to a non falsy value?
See here and here...

[tntrex]

Unfortunately, it's not working now with PICKLE_PECL_UNSAFE. Composer's downloader denies usage of http connection, because of secure-http option which is only disabled for "test server"

PICKLE_PECL_UNSAFE=1 ./pickle.phar install event -vvv
